Ron Palillo, who played Ronald Harshack on the hit 70's show "Welcome Back Kotter" was found dead this morning at his Palm Beach Gardens, Florida home. The actor was 63.

He was found by his friend Stacy Sacco around 4:30 a.m.

The death was caused by a heart attack.

According to friends, he has not been sick or ill lately, but it had been reported he had a bad cough and was going to go to the doctor today.

He leaves behind his longtime partner of 41 years Joseph Gramm, who is a retired actor.

Welcome Back Kotter aired from 1975-1979 and was the show that catapulted John Travolta to superstar success. Palillo played Horshack, who was a member of the group called The Sweathogs.

He will forever be remembered as a Sweathog and for going "ooh, ooh, ooh, Mr. Kotter" as his catchphrase on the show.-DocFB
